How to detect that the opponent computer says 'gg' and accept that?

When training the agent, we find that sometimes the opponent says 'gg' which means we win. Is there a way for the agent to accept this surrender now? Thank you !

No file or test is named in the issue. Start by locating the protocol definitions for opponent chat and surrender events, then determine whether the client exposes a surrender signal; done means the agent can recognize the opponent's surrender and accept the resulting win.
